Mounted on the member 26 immediately At 3 is shown a plate having a large central below tubes 30 is a horizontally disposed opening 4 therein and having an upstanding plate 31 terminating in vanes 32 disposed at annular boss 5 formed thereon to form shoulan angle whereby to move air upwardly ders at 6 and 7. Passages as 8 are formed through member 15 to the discharge ends of through the part 5 and controlled by a the tubes 27 and 30, this plate being disposed 0 damper9wherebytopermit airtopass therebelow the plane of the flange 16, an the tubes being disposed in such a manner that their discharge nozzles are above said plane. This plate also has a number of openings as 33 formed therein adjacent member 26, being formed by striking lips as 34 downwardly therefrom to lie at an angle directed forwardly in the direction of rotation of the plate whereby to move air upwardly from the member 15 to the space immediately surrounding member 26.

At 35 is a second plate mounted on member 26 in parallel relation to plate 31 and above tubes 27 and terminating in vanes 36 disposed at an angle whereby to move air from above the plate downwardly to the discharge nozzles of the tubes, these vanes alternating with downwardly directed and angularly disposed vanes 37 adapted to move-air from between plates 31 and 35 outwardly toward the discharge nozzles of the several tubes. The plate 35 is of less diameter than plate 31 to secure the free movement of the air stream over flange 16 and the proper diffusion of the air and fuel mixture through the fire-box.

The mixture to be burned is fed to the tube 22 through passage 21 and a conduit 38 from a source of supply not shown.

Through the wall or apron 10 are passed the electrodes 39 and 40, these electrodes being connected to a source of electrical energy not shown and terminating at a point immediately below the plane of the plate 3 and below the opening 4. At 41 is a tube leading from a source of supply of combustible mixture, not shown, to a point immediately below the terminals of the electrodes 3940 and directed upwardly between the same whereby material discharged from the tube 41 will pass upwardly between the electrodes and be ignited by the electrical current passing from one to the other, and in turn ignite the comb ristible mixture discharged from the tubes 2 -30.

When the device has been assembled as described and is in full operation, a fluid mixture of atomized fuel oil and air is fed to the tube 22 under pressure. From the tube it passes through the passage 23 to the small chamber 24 and thence into the tubes 27. The discharge of the fluid mixture under pressure from the several tubes causes the member 26, and all of the parts mounted thereon, to spin in the direction indicated by the arrow at 42. This spinning movement in turn creates air currents flowing in the directions indicated by arrows 43, 44 and 45, which air is intimately mixed with the mixture discharged from the tubes and the whole thrown out to the limits of the fire-box in an unbroken, circular sheet of flame.

The additional amount of air that is required to secure complete combustion is introduced into the burning mass through the annular space 17, the air being fed through as desired by controlling the openings 8 through the medium of damper 9.

The air flow at 43, 44, 45 1s such that the parts in the center of the device are always kept cool, with obvious advantages.

Another advantage of the construction and arrangement shown is that by using suitable automatic devices an initial charge of combustible mixture may be discharged through tube 41 and ignited electrically, and this charge is so placed and directed that it will immediately ignite the main fuel charge and be automatically cut off after the lapse of a predetermined period of time.

The structure at 28, 29, 30 is provided to catch any leakage of fuel downwardly below the tubes 27 on the inside of member 26 and throw it out into the burning mixture. This is readily accomplished because any material flowing down on the inner side of member 26 will be carried outwardly to the tubes 30 and thence to the discharge ends of the tubes by the centrifugal force developed by the spinning of the member and parts mounted thereon.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form, construction, and method of assembly and operation may be made within the scope of the appended claims.
